[RFC9110](https://www.rfc-editor.org/rfc/rfc9110.html#section-5.1) states header names are case insensitive. If a response header is defined with the name `"Content-Type"`, it SHALL be ignored. |

The key is a media type or [media type range](https://www.rfc-editor.org/rfc/rfc9110.html#appendix-A) and the value describes it. For responses that match multiple keys, only the most specific key is applicable. e.g. `"text/plain"` overrides `"text/*"` |
